The SG90 Plastic Gear Servo Motor is an low cost servo in a compact package. It is commonly used in light-weight radio controlled planes, helicopters, drones and robotics. This is the perfect servo motor to use in microcontroller mechatronic projects where limited space is available, there isn't a need for large amounts of torque and servo accuracy is required. Features of the SG90SR 180 Micro Servo: 180 degree rotation It can lift up to 1.5kg of weight positioned 1cm from the center of the shaft Small size Every motor is inspected and the basic operation verified Package includes: 1 - SG90SR Servo motor with attached 250mm control cable 3 - arms/horns for various interface applications Screws for mounting arms to the servo and mounting the servo to your project Motor Connections: The attached cable has a 3-pin female connector that is mated with a standard 0.1 male header. 1 Female Connector Brown = Ground Red = 5V Orange = PWM Signal.
